基于ZYNQ 7000的S波段USB应答机设计
|
摘要
文章目的在于在ZYNQ 7000的基础上设计一款小型的S波段USB应答机,以缩小应答机的体积,降低应答机的功耗;文章首先对于ZYNQ的优势做了简单的介绍,并基于ZYNQ 7000提出了USB应答机的设计方案,论述了调制、解调中的关键技术和工作原理;应答机工作过程如下:卫星进入在轨飞行段时,应答机接收地面测控站发射的上行遥控副载波信号,解调后将遥控PCM码流通过与卫星其他分系统接口发送至相关设备;接收地面测控站发射的上行测距信号,将变频后的测距基带信号进行本地上变频后对地发送;通过UART串口接收PCM遥测数据,将调制后的遥测数据通过遥测副载波发送至地面站;同时,将内部的遥测信息通过串口发送至其它分系统;即该应答机在非扩频模式下具有测距、解调遥控指令和发射遥测副载波的功能;应答机上下变频部分采用了集成的芯片,将电路进行了简化;ZYNQ及集成芯片的使用都大大地缩小了应答机的体积,降低了应答机的功耗。
The purpose of the article is to design a small S-band USB transponder on the basis of ZYNQ to reduce the size of the transponder and ruduce the power consumption of the transponder;This paper firstly introduces the advantage of ZYNQ,and puts forward the design scheme of a standard USB transponder based on ZYNQ 7000,and discusses the key technology and the principle of modulation and demodulation of the transponder.The working process of the transponder is as follows:when the satelite enters the on-orbit flight stage,the transponder receives the uplink remote control subcarrier signal transmitted from the ground monitoring station,and after demodulation,transmits the remote control PCM sream to the relevant equipment through the interface with other satellite subsystems;the transponder receives the uplink ranging signal transmitted from the ground monitoring station,the ranging baseband signal is transmitted to the ground after local frequency upconversion;the PCM remote data is received through the UART serial port,and the modulated telemetry data is sent to the ground station through the telemetry subcarrier;the internal telemetry information is sent to other subsystems through the serial port.That is,the transponder has the functions of transmit distance、demodulate remote control commands and transmit telemetry subcarrier in non spread spectrum mode;The transponder's up conversion part and down conversion part use the integrated chip,to simplify the circuit.The use of the ZYNQ and the integrated chip greatly reduced the volume of the transponder and ruduce the power consumption of the transponder.
